Platonov D. Minakov A. Dekterev A.Numerical investigation of spatial unsteady flows in hydraulic turbines of high-head power developmentReporter: Platonov D.
There is no way to increase stability and efficiency of the hydraulic machines without studying the physical mechanisms of hydrodynamic processes, including very important transient phenomena, associated with the formation of large-scale vortex structures. One of the mechanisms for generation of pulsations is precession of vortex bundle, which formed behind the runner in underload or overload conditions of the turbine, where the flow after passing through a water turbine has a large residual twist.
